Kalpa
Kalpa is one of the six Vedangas, dealing with ritual, ceremonies, and the procedures for Vedic rites and sacrifices.
- Kalpa is the Vedanga of ritual procedure — the practical guide to performing Vedic ceremonies correctly.
- It is called the 'hands of the Vedas' — providing the practical implementation of Vedic injunctions.
- Divided into four categories: Shrauta Sutras, Grihya Sutras, Dharma Sutras, and Shulba Sutras.
- Shrauta Sutras describe the major public sacrifices (yajnas) like the Ashvamedha and Agnishtoma.
- Grihya Sutras cover domestic rituals — birth, naming, education, marriage, and death ceremonies.
- Dharma Sutras lay out rules of conduct — the basis of later Dharmashastra tradition.
- Shulba Sutras contain precise geometric rules for constructing Vedic fire altars — some of the earliest recorded geometry.
- The Baudhayana Shulba Sutra contains what is effectively the Pythagorean theorem, centuries before Pythagoras.

Dharma Sutra — Duties of the Four Ashramas
Apastamba Dharma Sutra · Chapter 1 · Verse 1
ब्रह्मचर्यं गार्हस्थ्यं वानप्रस्थः संन्यासश्च। एते चत्वार आश्रमाः। ब्रह्मचर्यं विद्याभ्यासः, गार्हस्थ्यं गृहस्थधर्मः। वानप्रस्थः वनवासः, संन्यासः सर्वत्यागः॥
brahmacaryaṃ gārhasthyaṃ vānaprasthaḥ saṃnyāsaś ca | ete catvāra āśramāḥ | brahmacaryaṃ vidyābhyāsaḥ, gārhasthyaṃ gṛhasthadharmaḥ | vānaprasthaḥ vanavāsaḥ, saṃnyāsaḥ sarvatyāgaḥ ||
The four Āśramas (life-stages) and their duties: (1) Brahmacarya — student stage: celibacy and Vedic learning; (2) Gārhasthya — householder stage: marriage, children, social duties; (3) Vānaprastha — forest retirement: gradual withdrawal; (4) Saṃnyāsa — renunciation: complete withdrawal from worldly life. The Āpastamba and Baudhāyana Dharma Sūtras detail the specific duties of each stage.
Grhya Sutras — The Sixteen Life-Rites (Samskaras)
Ashvalayana Grhya Sutra / Paraskara Grhya Sutra · Chapter 1 · Verse 1
गर्भाधानं पुंसवनं सीमन्तोन्नयनम्। जातकर्म नामकरणं निष्क्रमणमन्नप्राशनम्। चूडाकर्म कर्णवेधोपनयनं च। वेदारम्भः समावर्तनं विवाहः च। वानप्रस्थः संन्यासो मृत्युसंस्कारश्च — षोडशैते॥
garbhādānaṃ puṃsavanaṃ sīmantonnayanam | jātakarma nāmakaraṇaṃ niṣkramaṇam annaprāśanam | cūḍākarma karṇavedhopanayanaṃ ca | vedārambhaḥ samāvartanaṃ vivāhaḥ ca | vānaprasthaḥ saṃnyāso mṛtyusaṃskāraś ca — ṣoḍaśaite ||
The sixteen Saṃskāras (life-purification rites) as prescribed in the Gṛhya Sūtras: (1) Garbhādhāna (conception), (2) Puṃsavana (foetal rite), (3) Sīmanta (parting of hair), (4) Jātakarma (birth), (5) Nāmakaraṇa (naming), (6) Niṣkramaṇa (first outing), (7) Annaprāśana (first solid food), (8) Cūḍākarma (head-shaving), (9) Karṇavedha (ear-piercing), (10) Upanayana (sacred thread), (11) Vedārambha (beginning Vedic study), (12) Samāvartana (graduation), (13) Vivāha (marriage), (14) Vānaprastha (forest retirement), (15) Saṃnyāsa (renunciation), (16) Antyeṣṭi (last rites).
The Four Divisions of Kalpa
Kalpa Vedanga — Introduction · Chapter 1 · Verse 1
श्रौतसूत्राणि, गृह्यसूत्राणि, धर्मसूत्राणि, शुल्बसूत्राणि च। एते चत्वारः कल्पस्य विभागाः। यज्ञविधानं कल्पः — इति लक्षणम्॥
śrautasūtrāṇi, gṛhyasūtrāṇi, dharmasūtrāṇi, śulbasūtrāṇi ca | ete catvāraḥ kalpasya vibhāgāḥ | yajñavidhānaṃ kalpaḥ — iti lakṣaṇam ||
Kalpa (ritual procedure) is divided into four categories: (1) Śrauta Sūtras — public fire rituals based on the Vedas; (2) Gṛhya Sūtras — domestic rituals and life-cycle rites; (3) Dharma Sūtras — social law and duties; (4) Śulba Sūtras — geometry for Vedic altar construction. Kalpa is the hand of the Veda — it enacts what the Veda prescribes.
Dharma Sutra — Four Sources of Dharma
Apastamba Dharma Sutra / Manu Smriti · Chapter 1 · Verse 1
वेदः स्मृतिः सदाचारश्च स्वस्य च प्रियमात्मनः। एतच्चतुर्विधं प्राहुः साक्षाद् धर्मस्य लक्षणम्॥
vedaḥ smṛtiḥ sadācāraś ca svasya ca priyam ātmanaḥ | etac caturvidhaṃ prāhuḥ sākṣād dharmasya lakṣaṇam ||
The four sources of Dharma: (1) Veda (scripture), (2) Smṛti (remembered law texts), (3) Sadācāra (good conduct of the virtuous/learned), (4) Priya ātmanas — what is pleasing to one's own soul (conscience). These four, in order, are the direct definition of Dharma. Based on Manu Smriti 2.12 and related Dharma Sutra passages.
